title: Successful treatment of pure red cell aplasia after major ABO-incompatible T cell-depleted bone marrow transplantation with erythropoietin.
abstract: A 40-year-old woman with acute myeloid leukemia in first remission developed pure red cell aplasia after a T cell-depleted ABO-incompatible bone marrow transplant from her HLA-identical sister. She remained transfusion-dependent for 11 months despite conversion of the ABO blood group to donor type, and titers of anti-donor isohemagglutinin being undetectable. Treatment with erythropoietin resulted in rapid improvement of the anemia with no further need for transfusions up to 21 months post-transplant. This case suggests that erythropoietin may provide effective therapy for pure red cell aplasia after ABO-incompatible bone marrow transplantation without the additional risks of further immunosuppression.
